According to the regulator, water bills in England and Wales will climb by 36% by 2030. This surge is driven by suppliers’ efforts to address pollution challenges and escalating debt burdens.
Ofwat announced that water charges will rise by £157 over the next five years, translating to an approximate £31 annual increase. Consequently, the typical yearly bill is expected to jump from £440 to £597.
This final decision follows Ofwat’s July draft proposals, which had permitted water companies to raise bills by an average of 21%, excluding inflation, over five years. These funds are intended to support an £88 billion investment to enhance services and environmental initiatives.
In October, it was revealed that water companies had initially sought a larger average hike of 44%, amounting to an additional £39 per year.
The proposed rate increases are scheduled to begin in April next year.
Thames Water, serving around 16 million residents in London and the South East, is under particular examination as it strives to secure a £3 billion bailout from creditors.
The company is grappling with a financial crisis that may deplete its funds by March. Currently, Thames Water is burdened with over £16 billion in debt, a figure that is expected to rise further if the court approves the rescue package in February.
